A method to improve the consistency of wire dicing data for large silicon wafers

ActiveCN116817729BImprove consistency testing issuesSolve the problem of being unable to characterize the deflection of the cutting directionElectric/magnetic roughness/irregularity measurementsFine working devicesConsistency testWire cutting
This invention provides a method to improve the consistency of wire-cutting data for large silicon wafers, addressing the problem that existing testing methods cannot provide consistent test data with the wire-cutting direction as the initial position for process debugging and R&D needs. A method is proposed that solves the wire-cutting data consistency problem by changing the initial test position and aligning the test path with the cutting direction, thus facilitating process adjustment and optimization of processing parameters. The initial test angle β is adjusted so that the angle α between the initial test angle and the notch direction is equal to β. The thickness steepness of the test data along the cutting direction is calculated to characterize the impact of cutting on the silicon wafer morphology.

A crack suppression based machining parameter optimization method

To overcome the shortcomings of existing technologies in formulating optimal processing schemes that effectively suppress the initiation of service cracks, thus posing a potential safety hazard to metal components, this invention proposes a processing parameter optimization method based on crack suppression. Using in-situ tensile and SEM techniques, the core indicators of crack initiation during the service of metal components are taken as the direct targets for processing parameter optimization. This reveals the influence of differences in surface condition caused by processing parameters on microcrack initiation. Based on this influence, strain-crack density curves are established under different processing parameter combinations / parameters to screen out the optimal processing parameter combination / parameter. If the optimal processing parameter combination / parameter cannot be screened, the correlation between crack initiation point, surface damage type, and processing parameter combination / parameter is further established, and the optimal processing parameter combination / parameter is screened based on this correlation.
